Operon evidence: Northern blotting (2.8 kb and 3.3 kb transcripts)
Reference: Petersohn A, et al. (1999)
Comments: The readthrough terminator downstream of ydaE leads to a 1.6 kb transcript. Both ydaDEFG transcripts terminate before reaching ydaH. An internal promoter in front of ydaG leads to monocistronic ydaG transcripts of 0.47 kb, 0.6 kb, and 0.9 kb. A 1.6 kb ydaFG transcript was also detected.
